. or WORCESTER, MASSACHUSETTS, A CORPORATION OF MAssAcHusErTs BOX GUIDE Foal-com LAYS Application fil ed. November 22,192s., seriarrro. 32mm- This invention relates to improvements in box guides used on the lays of fancy or drop box looms and it is the general object of the invention to provide ready means for setting the boxes so theywill deliver the shuttle cor rectly with'respect to the reed.

r In the usual box-loom the lay is constructed of a wooden beam to the ends of which may" be secured a so-called lay end made prefer- Thebox end of afancy. loomlay usually employs a rather large casting secured to the lay sword and lay beam and having guides extending vertically in which slide the tongues of the shifting boxes. These guides;

as ordinarily constructed havebeen made im movable with respect to the lay end and it has been necessary to move or bend the latter whenever an adjustment of the guides was required. There is ordinarily no support for the outer end of the lay so that there may be a considerable length of metalfextending beyond the crank and lay "sword which is unsupported and therefore tends. to move back and forth due to itsrnomentum as thela-y reaches the rear and front extremities. of its motion. It is found that in certain ins'tances this tendency on the part of the lay end to move relatively to the lay beam results in in- 5 correct alignmentof the boxback, a condi-j tion which can be corrected in present con-i structions only by a rather awkward pro-j cedure of either bending the whole lay end relatively to the lay beam or taking down the lay end and changing its positionby the insertion of shims. It is animportant object of my present invention to provide a box guide which shall be separate from and movable back and forthrelativelyto the lay end so that the boxes may be quickly'and easily positioned relatively to the reed'line. V

The back of the box ordinarily is not in true alignment with the reed assuch a con-- struction might result in causing the shuttle .itofly outof the loom.- In order to prevent this action on they part ofthe shuttle the outer end of the box back usually lies slightly forwardof the reed line, this construction tending to push the shuttle toward theree'd to be held .contactwiththelatter throughout its flight throughthe shed. ,B'ec'au'se of readily this adjustment;

I have shown herein means i the outer guide of thebox' but the principle set'forth herein may be equally applicable to the inner guide near the reed and'I do, not wish to be limitedto. the particular form of,

my invention as shown herein.

xWith:these andother objects in View which i will appear as the description proceeds','my

for varying invention resides in the combination and ar} rangement of parts hereinafter described-and set rennin theclaims.

In the accompanylng drawings wherein have shown two forms of theinventionk v l is a front elevationof one end of; a lay having myinvention applied thereto,

Fig. -2 is a top plan viewof Fig l showingi the. outer-portion of the lay, and

in section for the sake of clearness. I Referring to Fig. 1, I"have shown a loome side 10 andarocker shaft 11 to the'left end' ofwhich is secured: the rockeriron 12; v A lay sword 13 moves aroundthe axis of the rocker shaft 1 1; and extends upwardly to havese' cured thereto the laybeam 14; which maybe made of wood. v As;shownparticularly in Fig. 2 there-extends to the leftfof the lay wood a lay endmeinber 15 to which is secured a block 16. Said block has attached to the Fig. 3 is atop planviewof Fig. 1, showing rw a e 7 hsrt e fi new v ih 9? the most part is of the usual construction.

The lay is provided adjacent the reed R with a guide 19 having a vertical slot 20 which receives a complementarily formed tongue 21. Said tongue is on the inner end of the gang of boxes B and guides the latter. The reed R defines the path along which the shuttles should move across the loom and the boxes which may be formed as a single integral casting are provided with a common back 22, the forward wall 23 of which is to be kept in proper relation with respect to the reed R. The boxes may be reciprocated by a rod 24 operated by mechanism not shuttles whenbrought to position one at a During the normal running of the loom the boxes B will be moved in a vertical direction so that the tongue 21 will move in the slot 20 of the guide 19,"thereby holding the inher end of the boxes in correct positionwith respect to the reed. The matter thus far described forms no part of my present invention and may be of usual construction.

feet I provide the plate 18 with a rear vertical extension'4O and provide forthe latter a movable guide element 41. The latter is formed with a slot 42 somewhat similar to the slot 20 and guide 19, said slot 42 receiving the tongue 43 of the boxes. The guide element 41 is separate from the plate 18 and its vertical extension or projection 40 but is' held to the latter by means of a pair of bolts 44 and 45 which are located respectively at the upper and lower'ends of the guide plate Each of the bolts 44 and 45 passes through a horizontal slot 46 formed in the rear extension 40 and the head of the bolts are sufliciently large to prevent passing of the latter through these slots. The inner or right'ends of the bolts are threaded into the element 41 as shown at '47 in Fig.3. I

The bolts 44 and 45 are movable horizontally in and held againstmovement in a verrotation of the .bolt 44 which would disturb the proper setting of the guide element. The same relation exists for the lower bolt 45 and the adjusting screws for both bolts may be held in position by lock nuts 5O. A

. When assembling the .parts shown par ticularly in Fig. 3 the guide element .issev curedto the extension 40 before the, boxes 13 are put in place and given an approximate time may be propelled by the picker stick setting in a horizontal direction. The boxes may then be placed as shown in Fig. 3 with the tongues 21 and 43 in their respective guide slots and a gauge applied to the box to determine its relative position with respect to the reed. If the outer end of the box is forward too far with respect to the reed the rear screws 48 may be turned backwardly and the front screws 49. turned to move the bolts 44 and45 rearwardly until the surface 23 0f the boxes assumes the proper relative position with respect to the reed B. When in correct position the rear screws 48 may be i set up tightly against the bolts 44 and 45 and shown but acting througha link 25 and the the lock nuts 50 moved to position to holdall of the several parts rigidly in proper position. Should the outer end of the boxes be behind the improper position the correspond ing adjustment may be made, the element 41 being moved relatively to theextension 40 and "being held in adjusted position by the bolts and screws.

If during the running of the loom it is noticed that the shuttle flies out of the shed be cause of the fact that the outer end of the v box is behind its correct position, the element In carryingmy present lnvention 1nto ef- 41 may be moved forwardly in the'manner described. Conversely, if it is noticed that the rear shuttle is wearing too much because the angle between the surface 23 and the reed had become too great the element 41 can be moved rearwardly." It will be noticed that the positioning of the boxes with respect to the reed is accomplished without bending the lay end 15 and without disturbing the relative position of the block 16 and plate 18 with respect to the lay beam 14.

. From the foregoing it will be seen that I have provided a very simple means for.

varying the angular position of the boxes with respect to the reed without-requiring bending of the" lay same with respect'to the lay beam. It will also be seenthat the guide element can be moved to a plurality of positions and that when in a final position is held tightly against an'extension 40 by means of bolts 44 and 45 and it will further be seen that the latter are held 'against'rotation and are therefore locked in their proper position by the adjust-v ing screws 48 and 49. While I have shown the guide element as being movable relatively to 1 the layand located on the outer end of the boxes yet I do not wish to be limited to this particular location of the movable guide element. Furthermore, the portion of the construction which is moved to secure correct alignment is supported directly by the lay and the tongue which cooperates therewith is integral with the boxes, but I do not wish to be limited to this construction as it is within the scope of my present invention to provide an adjustable connection between the box and the lay in the, form of a movable eleend or resetting of the-- ment which may be secured either to the box or the lay end.

Having thus described my invention it will be seen that changes and'modifications'may be made therein by those skilled in the art without departing from the spirit and scope of the invention and I do not wish to be limited to the details herein disclosed, but what I claim is: y
